IT chanced on Sunday, when Mr. Utterson was on his usual walk with Mr. Enfield, that their way lay once again through the by-street; and that when they came in front of the door, both stopped to gaze on it.

It was impossible to do the one without the other, returned Enfield. And by the way, what an ass you must have thought me, not to know that this was a back way to Dr. Jekylls! It was partly your own fault that I found it out, even when I did.

So you found it out, did you? said Utterson. But if that be so, we may step into the court and take a look at the windows. To tell you the truth, I am uneasy about poor Jekyll; and even outside, I feel as if the presence of a friend might do him good.

The court was very cool and a little damp, and full of premature twilight, although the sky, high up overhead, was still bright with sunset. The middle one of the three windows was half-way open; and sitting close beside it, taking the air with an infinite sadness of mien, like some disconsolate prisoner, Utterson saw Dr. Jekyll.

You stay too much indoors, said the lawyer. You should be out, whipping up the circulation like Mr. Enfield and me. (This is my cousinMr. EnfieldDr. Jekyll.) Come, now; get your hat and take a quick turn with us.

You are very good, sighed the other. I should like to very much; but no, no, no, it is quite impossible; I dare not. But indeed, Utterson, I am very glad to see you; this is really a great pleasure; I would ask you and Mr. Enfield up, but the place is really not fit.

That is just what I was about to venture to propose, returned the doctor with a smite. But the words were hardly uttered, before the smile was struck out of his face and succeeded by an expression of such abject terror and despair, as froze the very blood of the two gentlemen below. They saw it but for a glimpse, for the window was instantly thrust down; but that glimpse had been sufficient, and they turned and left the court without a word. In silence, too, they traversed the by-street; and it was not until they had come into a neighbouring thoroughfare, where even upon a Sunday there were still some stirrings of life, that Mr. Utterson at last turned and looked at his companion. They were both pale; and there was an answering horror in their eyes.
